Celestia - Model WizardLink -Multi-Channel Data Transmission Unit for Satellite Equipment

SHARE

The WizardLink Front-End provides high-speed serial interfaces to spacecraft flight equipment. The Front-End is used during spacecraft assembly, integration and test phase to test and validate satellite flight equipment. Typically, the WizardLink Front-End connects to a Payload, Mass Memory Unit, Laser Communication Terminal or RF Transponders. This Front-End operates as a data source (transmit), data sink (receiver) or both at the same time.

The system consists of a 19″ 2U rack-mountable unit that is controlled and monitored by a software application that allows the system to be used stand-alone or controlled remotely via a Central-Check-Out System (CCS). 

Providing up to four (4) WizardLink channels in parallel the Front-End interfaces directly to the unit under test (UUT) on one side using differential Voltage Mode Logic (VML) and exchanges user data on the other side using a 10Gbit TCP/IP streaming interface. 

The Front-End enables the user to transmit or receive data (such as CCSDS Frames, Packets, etc.) to/from any source. Using a commercial server platform data recorded from the WizardLink channel(s) is offloaded using a standard 10Gbit TCP/IP interface and stored to disk and vice-versa. The commercial 10Gbit ethernet interface allows both copper or optical interfaces between the Front-End and the server platform. This allows the data to be transported over long distances (300 meters or longer) between front- and back-end.

Providing electrically isolated VML interfaces including fail-safe protection to protect transceivers in their power-off state, the WizardLink Front-End provides satellite level fault voltage emissions and tolerances. 

In the second quarter of 2019, it is foreseen to support the SpaceFibre protocol (compliant to ECSS-E-ST-50-11C).
